VACUUBRAND™ MV 2 NT Membranpumpe

Beschreibung

Typical applications for chemistry diaphragm pumps include evacuating chemically aggressive gases and vapors from such equipment as rotary evaporators, vacuum drying cabinets and centrifugal concentrators. Chemistry diaphragm pumps from VACUUBRAND feature uncompromising chemistry designs. Their construction with fluoropolymers makes them very resistant to chemical vapors from inlet to exhaust and very tolerant to condensates. Our two-, three- and four-stage pumps also have a gas ballast valve that provides continuous purge with minimal impact on ultimate vacuum when working with condensable vapors. Pumping chambers are hermetically separated from the drive system ensuring long lifetimes of mechanical parts. Most importantly, diaphragm pumps are oil-free, for vastly reduced service demands compared with oil-sealed pumps. They eliminate the cost of water and its contamination well-known from water-jet aspirators, and the waste-oil disposal of rotary vane pumps.

• Innovative connections in the new NT models ensure very low leak rates for excellent flow rates under vacuum and long-term performance stability, even after thousands of hours of service
• No abrasion, making it dust- and contamination-free
• Long diaphragm and valve lifetimes:Made of highly flexible FKM, with fabric-reinforced double diaphragms for improved long term stability
• New patented drive support system in NT pump models provide for uniquely quiet, low-vibration operation
